Re: IJC/OPM How do you lighten a profile

2005-02-04 by bwbonkers

Hi Joe / nick

Many thanks for your help. I think now I have a better understanding 
of what the aims slider does. To lighten my test print to match my 
monitor I have moved the aims down -4, which has remapped the L 
values, step 13 from 50 to 40. If I keep my original linear profile 
(aims set to 0) and print in OPM with the exposure slider set to 
lighten by 10 units, I get a very similiar print. This begs the 
question, is the exposure slider doing a similiar job as the aims 
slider. Hmm....

Peter.
